Create a tree view in c# on SharePoint Online Document Library Basis with CSOM

Question

I want to create a Treeview in C#. My basic data is stored in a SharePoint Online DocumentLibrary. I authenticate with a user and I want to show the folders and files as a tree view in Azure function where the user has the permissions to. On that bases the user should see the following tree.

The view should be like that:

 Folder1
      Folder11
         Document.docx
         Document.pdf
      Folder12
         Document.xslx
   Folder2
      Folder21
      Folder22
        Folder221
            Document.json
        Folder222

etc.

Maybe you can help me with this approach.

Thanks

Matthias

You can refer to following code to enable tree view

clientContext.Web.TreeViewEnabled = true;
clientContext.Web.Update();
clientContext.ExecuteQuery();
